2. Soldering the headers Before using your click board, make sure to solder 1x8 male headers to both left and right side of the board. Two 1x8 male headers are included with the board in the package. 1 4. Essential features GPS3 click 2 3 The L80 module aboard GPS3 click incor- porates several technologies that enhance 1. Introduction the GPS performance. EASY Technology ensures that L80 can calculate and predict orbits automatically using data stored in its internal flash memory.

The Automatic the bottom side is facing you upwards. to align the headers so that they are antenna switching function enables Place shorter pins of the header into the perpendicular to the board, then solder switching between the internal patch anten- appropriate soldering pads. the pins carefully. na and the external active antenna, keeping positioning during the switching process. GPS3 click carries Quectels L80, a high-sensitivity ultra slim GPS module 3. Plugging the board in with a patch antenna. With it, you can add click GPS functionality to your design without Once you have soldered the headers your the need for an external antenna (although board is ready to be placed into the desired BOARD the click board has a connector for one mikroBUS socket. Make sure to align the www.mikroe.com should you require it). An onboard red LED cut in the lower-right part of the board with will blink to indicate successful satellite the markings on the silkscreen at the GPS3 click manual acquisition. GPS3 click communicates mikroBUS socket. If all the pins ver. 1.00 with the target board through mikroBUS are aligned correctly, push the UART (RX, TX) and RST lines. The board is board all the way into the socket. 0 100000 027318 designed to use a 3.3V power supply. 5. GPS3 click board schematic 6.
